Title: Manufacture of quartz glass crucible
Inventor: ABE HAJIME
IPC: C30B15/10
Filed: 1987-12-15
Abstract: PURPOSE:To obtain the title crucible free from bubbles and having high granularity by introducing H2, He, or their gaseous mixture from at latest the start of melting of grains at the time of adding the grains into a hollow die. CONSTITUTION:The hollow die 6 is rotated around a vertical shaft in the direction as shown by arrow 3 by using a rotary driving device 1. Grains are continuously or discontinuously added to the hollow die 6 so that the grains are layered on the inner wall of the hollow die 6 and accumulated on the bottom, and a grain layer 7 in the form of a crucible is formed. The heat of a heating source 8 is applied from the inside toward the outside through the thickness of the grain layer 7. H2, He, or their gaseous mixture is introduced from an injection port 10 from at latest the start of melting of the grains. As a result, only a part of the grain layer 7 is melted, the thin layer part is sintered, and the remaining grain layer 7 is kept in a state of grains as it is. The obtained quartz glass crucible is cooled, and then taken out from the hollow die 6.

Title: Corrosion resistant steel
Inventor: YAMASHITA MASATO
IPC: C23C22/00
Filed: 1997-11-17
Abstract: PROBLEM TO BE SOLVED: To improve the corrosion resistance of a steel not only in atmospheric corrosive environments but also in seawater-splashed parts and in seawater by coating the surface of the steel with dense α-(Fe,Cr)OOH contg. a specified amt. of Cr, low in free energy and excellent in serf-recoverability. SOLUTION: The surface of a steel is coated with α-(Fe,Cr)OOH contg. 1.5 to 28.0 mass% Cr. This α-(Fe,Cr)OOH is the one low in free energy, stable and not deteriorated even in seawater, and in which the bonding among the crystals is strengthened to increase the cohesiveness thereof, and the state that seawater in filtrates and reaches the surface of the steel is prevented to improve the corrosion resistance of the steel to seawater. Moreover, even in the case defects are generated in the α-(Fe,Cr)OOH layer caused by any damage, Cr is diffused to be supplied from the layer into FeOOH formed at the defected part to recover the defected part. The coating of the α-(Fe,Cr)OOH is formed by applying an aq. soln. of chromium (III) sulfate on the surface of the steel for plural times.

IPC: H02K37/14
Filed: 1991-11-29
Abstract: PURPOSE:To reduce the noises of a rotor when it rotates by reducing the detent torque of a small stepping motor. CONSTITUTION:The difference between a magnetic reluctance existing between the outer yolks or between the inner yolk and the outer yolk, and a magnetic reluctance existing between the inner yolks is reduced by means or the like whereby the length of the pole teeth 12a and 12b of the outer yolks of a stepping motor in the width direction and axial direction are made larger than that of the pole teeth 11a and 11b of the inner yolks, and then, the area of the pole teeth 12a and 12b of the outer yolks is made larger than that of the pole teeth 11a and 11b of the inner yolks. As a result, there is an increase in the numbers of magnetic fluxes which leak from the magnetic poles of the rotor across the pole teeth 12a and 12b of the outer yolks or across the pole teeth 11a and 11b of the inner yolks and the pole teeth 12a and 12b of the outer yolks. Thus, as compared to the conventional stepping motor, the amount of the detent torque variations is reduced.
